Hey everyone, I just released a package that adds support for animating VisualElements with Timeline: https://github.com/mihakrajnc/UITTimeline We've recently had a need to add more VFX / animations to our UI, and needed to give more power to our animators than the standard USS transitions provide (e.g. keyframing). The package is in very early stages but has proven to be very useful so far, so I've decided to officially release in the hopes it may prove useful to more people / animators out there. It contains a timeline track and clips that allow you to select and animate VisualElements - all transform values are supported, in addition to some commonly used styles, like Opacity, Visibility, and Display. It also allows adding / removing classes directly from Timeline. The selector syntax is similar to the way selectors work in Unity Style Sheets (USS). I would appreciate any advice / opinions / feature requests you may have!
